Asked by Feb 23, 2017 at 05:42 PM about the 2002 Pontiac Grand Am GT

Question type: Maintenance & Repair

My Pontiac Grand Am GT 2002 is
overheating I had changed the water pump
and the thermostat end my brother has
blood out the air three separate times. It is
been running fine for 2 weeks until just the
other day and it started overheating again
blowing out cold air through the vents. Now
ever since then it's been okay again today
had begin to overheat when we pulled over
and parked it and turned the car off I could
hear the air bubbles again making a popping
sound. I think it could be the cooling system
comma the fan, the radiator, or a head
gasket. I need feed back. It may be leaking

These engines are pretty notorious for blowing head gaskets. Pull the oil dipstick and see if there's white milky "goop" on the dipstick. If so, it's a head gasket. Also, with the engine cold, use a cooling system pressure tester and pressurize the cooling system to 15 PSI. It should hold the pressure for 15 minutes minimum. If not, look for where it's leaking. If no leaks can be seen start the engine. If the needle on the pressure tester gauge bounces it's a blown head gasket. HTH. -Jim
